The default location usually shown above is the Ordnance Survey
triangulation pillar at Danby Beacon on the North York Moors.

Drag the red marker to where you want a National Grid Reference.
It will appear on the right, with selected red or green boxes on the map.

Press the Satellite button to turn on the aerial photo's, or Hybrid for
combined road maps and
aerial photo's.
Use the + and - buttons to zoom in and out, and the arrows to pan.
You can also drag the map.

In the "Go to a National Grid Reference" box, you may use a 6, 8 or 10
figure GB Ordnance Survey NGR.

The above map can provide street view photographs by dragging the yellow person icon to a road.
The other method if you
wish to see if any street view photographs are near your selected
map location is to click the link immediately below the map. If you
use tabbed web page browsing, you can right click over the link,
then select "Open in a new tab". When
the Google Map page has loaded, it will be centred on your map
reference. Street view photographs are typically at road
junctions. In main towns and cities, they may also be on roads
away from road junctions. If a street view photograph is
available, when you select maximum zoom, an orange figure icon will
appear and the map view will switch to a photograph of that road or
road junction.

"Link to this
location" will be visible when grid references are
displayed. You can right click over it and copy the link to
your clipboard. You can then paste that link into an e-mail so
that others can see the map and the marker. The map style and
zoom level you selected will be seen by others who use that
link. Some examples are below.
